Sly Fox Brewery is an award-winning Pennsylvaniabrewery. The original Sly Fox Brewhouse & Eatery was founded by the Giannopoulos family at its original Phoenixville, Pennsylvania, location on December 20, 1995. The name of the establishment came out of a family meeting from the tradition of fox hunting in the Chester County area, where the first Sly Fox location resides.

Sly Fox opened a second location on November 8, 2004, in Royersford, Pennsylvania, right off Route 422, northwest of Philadelphia. The Phoenixville Brewhouse & Eatery moved "across the street" from the original location in 2010 which provided more space, parking and room for the annual Bock Fest and Goat Race.

Beer production capacity tripled in 2012 with the opening of the new brewery in Pottstown. The 30,000 sq. ft. brewery, situated on six acres at 331 Circle of Progress in the Pottstown Airport Business Center, is able to brew 50 hectoliters three times a day. A tasting room/pub has since been added.

On the first Friday of every month, and only on the first Friday, a single keg of Incubus Tripel is tapped at noon at the Phoenixville location. The Incubus is poured until it kicks, which has occurred fairly early for this popular event.

Started in Royersford in October 2005 but moved to Phoenixville in June 2006, a fresh firkin of a different cask conditioned Sly Fox beer is tapped on the bar on the third Friday of each month and poured until it runs out.

Dreamed up in 2003 by Corey Reid, the Phoenixville location's bar manager, the St. Patrick's Day Boot Camp is a nine- or ten-week program leading up to St. Patrick's Day that allows participants to earn raffle tickets for a drawing conducted on St. Patrick's Day. Starting in 2005, the grand prize is a trip for two to Ireland.

Each visit to Sly Fox earns the participant two raffle tickets and a stamp on their Boot Camp card, and participants can visit both locations. Starting in 2005, raffle tickets are given out on Wednesdays in Phoenixville and Thursdays in Royersford. After eight stamps, participants are given a Boot Camp T-shirt and ten additional raffle tickets.

Sly Fox's Robbie Burns Birthday Bash, held in January at Phoenixville every year since 2003, honors Scotland's greatest poet. The event marks the release of Gang Aft Agley Scotch Ale and Burns' Scottish Ale and features readings of Burns' poetry by attendees, bagpipes, and a menu of Haggis and other Scottish treats.

An all-day event held annually at Phoenixville, typically on the first Sunday in May, the Bock Beer Festival and Goat Race celebrates Bock-style beers and a traditional German menu. Originally the brain child of brewers David Sutula and Brian O'Reilly and launched in 1997 at the John Harvard's Brew House in Cleveland, Ohio. O'Reilly brought the idea with him to Sly Fox in 2002 after the Cleveland brewery closed. The event is held inside the pub and on the outside patio and parking area.

The event also features a multi-heat goat race competition in the adjacent parking lot. Owners run with the leashed animals but may not lead or pull them toward the finish line. The victorious goat earns the reward of having the brewery's annual Maibock named in its honor.

The 2005 event was greeted by sunshine, clear skies and spring temperatures, after a number of weeks where the area saw inclement weather. The good weather brought out an unexpected, record crowd of 1,000-plus people, a record 24 goats in the race, and the pub poured 13 barrels (403 gallons) of beer, putting a strain on the staff, supply of glasses, and restroom facilities. After learning some lessons in 2005, the festival in 2006 was greeted again by bright, warm sunshine and went smoother despite seeing nearly double the crowd from the previous year.[1]

At the 2014 event, a close finish and an officiating mistake resulted the wrong goat being declared winner. Immediately after the race, entrant "Spartacus" was announced as the winner, and the 2014 Maibock was named "Spartacus" in his honor.[3] Post-race video review revealed that the final was actually won by non-profit animal rescue Recycled Tails' entrant "Jixxer". Sly Fox released a statement apologizing for the error and announcing a special event and a beer named after Jixxer as restitution.

Started in 2004 as a year-long celebration of brewery's ninth year in business, Sly Fox created a series of eight varietal IPAs, each brewed with a single hop. All eight of the hops were used to brew Odyssey, Sly Fox's first Imperial IPA. The event culminated in an all-day festival at the Phoenixville location in December where the brewery's flagship Rt. 113 IPA, all eight varietal IPAs, and Odyssey were all available on tap.

In 2005, the IPA Project was repeated with nine varietal IPAs with nine new hops plus a reformulated Odyssey. The IPA Project celebration poured 12 different IPAs: Rt. 113 IPA, the nine varietals, and both the 2004 and 2005 Odyssey. The day-long event also marked the release of Rt. 113 IPA in 22oz bottles.

IPA Project 2006 repeated the best three single hop IPAs each from 2004 and 2005 and introduced four new ones, for a total of ten varietals. This year's day-long celebration in December was topped off with the first release of Odyssey Imperial IPA in 22oz bottles.

The 2007 version was hindered by a massive warehouse fire that occurred in October in Yakima, Washington, which destroyed roughly two million pounds of U.S. grown hops and has left several varieties in short supply or completely sold out for the year, but Brewery Operations Manager Tim Ohst announced that they planned on brewing eleven total varietals but in smaller batches. The IPA Project Day was held on December 14, 2007.
